Determination of mass attenuation coefficients for natural minerals from different places of Turkey
The mass attenuation coefficients (?m) for some natural minerals taken from different places of Turkey were measured at various low photon energies. The Am-241 radioactive source and Zr and Cd secondary exciter are used to get photons in the energy range 15.8 to 26.2 keV. For each sample and energy, Io and I intensities which are without and after attenuation were measured by a Si(Li) detector coupled to multi channel analyzer (MCA) using narrow beam transmission arrangement and mass attenuation coefficients were determined using these intensities. ©2011 Academic Journals.
